They could've meant a newcomer to the criminal underworld. At least that's the way I interpreted it, I think Leonardo would fit that description as well. He was exposed to his fathers schemes and business ventures as a legal counsel I think, not as an actual participant. So I think that he would fit that as well. Thats just my theory though. And do you know of anyone whom, as they describe, would have a "strong familial tie" to the Rizzutos aside from Leonardo? I don't mean to make it sound so tongue in cheek, this is a legit question.
